Fixed, I think. Now it's a bit smaller and has caps on the power rails (only 100uF electrolytics, though, didn't have room to shunt them with some 100nF ones or so). Little, if any, is left of the original abuse of curve tool, now replaced with abuse of diagonal traces. The component layout looks kinda prettier, it's fun making those:

If you add a 50k or 100k trimmer with the outer pins going to + and - and the middle pin to a 100k resistor and add that little circuit to the Main CV Line (where all the CV's mix or meet) you will make it work universal for all Voltage Power Formats. It will act as a Cutoff Range Offset.

No :/ The guy who tried to build it only got so far, but I haven't heard from him for a while. I think he had some problems with the power supply - he's a guitar stompbox guy, just like me. I'm hopefully gonna build my own bipolar PSU soon, though, so I'll eventually get around to testing it. Sorry :/

Hi:
I just finished my Polivoks VCF using this PCB and I can confirm it works.
I just did some mods to improve the cutoff range and the CV inputs sensitivity, but this mods are the same all people do to the Marc Bareille version.
Thanks again to egasimus for share!!!_________________Sebo

I've etched a board for this thing, but haven't found time to assemble it into a module (and since I want it to be a dual, will need to etch another board).

What mods did you do to improve cutoff range and CV input sensitivity? Will need to see if I can change the layout slightly to incorporate the changes. Would also be nice to have a euro style power connector, since I have them on the bussboards in my cabinets, that's an easy enough addition.

Edit:
Did you tie the cutoff to V- with a resistor? That's also a mod for the SSM2044 VCF, helps tremendously.

To imporve cutoff range I wired the side of the cutoff pot that goes to ground to -15V instead. Also changed R8 to 270K and put a 50K trimpot in series to finetune (I think I ended with a total resistance of 290K aprox).
To improve the CV sensitivity I changed R5 and R9 to 150K._________________Sebo
